However, there is not a common measure of that ratio amongst the Member States. This paper aims to analyse whether the CDD defined by Portugal is a reliable indicator for measuring the short-term financial sustainability of Portuguese local governments. The research is based on the IMF's transparency framework and European and Portuguese legislation on late payments. Statistical analysis was performed using Pearson's correlation and simple linear regression to assess whether the unpaid commitments of goods and services explain the short-term debts. Thus, by evaluating the budget and financial information consistency, the paper approach represents a novelty in this research area. The findings identify that the CDD of Portuguese local governments is not a reliable indicator of their short-term debt sustainability. The information is not consistent, and the indicator is permeable to creative accounting practices that give the illusion of a financial situation that may not be real.engaccountability, consistency, local governments, financial sustainability, transparency.Is the commercial debt default ratio a reliable indicator of the short-term financial sustainability of portuguese local governments?Czy współczynnik zadłużenia komercyjnego jest wiarygodnym wskaźnikiem krótkoterminowej zrównoważoności finansowej portugalskich samorządów lokalnych?journal article10.17512/pjms.2021.24.1.19
